PORATION OF vll/LSQINE.

BeV it: known that I, Jessi-H 'FRAUENrisLDibR,` 'a l'citiz'enf o f the.vUnitedf States, residing :1t-Bridgeport', the county .or F aireld andState' of ConneCticug-have invented certain newand-iisefiil Iiip'rove--ments in Submarine Boats, o f which' the following is a specification.-l

This invent-ion relates to an improvement in submarine orsubmersibleboats and -particularlyV to the construction, C arrangement,location andz controlof the`severalballast` tanks designed `forholdingvvateifballast for subine'rgingan'd 'trimming the boat.v

Heietofore, all submarine' ori submersible boats, so far as I am'aware,l have their mainV ballasbtanks located not only cent-rally but lboat', a peculiar constructiom arrangement;-

l/of `volume of the middle main ballast-tank 9 is arranged to liesubstantially in vertical.

alinement with the center of gravity of the boat and thel centers ofvolume of the forward and after middle main ballast-tanks will lieinlongitudinal vertical planes with the center of gravity and spaced anequal distance fore and aft of the center of gravity so that when wateris admitted to the center main ballast-tank, and equal quantitie ofwater ballast are admitted to the forward and after main ballast-tanks,the longitudinal and transverse trim 'of the boat will not be disturbed.

Built upon the main or inner hull and ex- '.,tending through the deck 3is a navigatingvturret 3 which communicates with the cent'r'al, controlcompartment through a hatch 3vf' (Fig. 1) and may be provided with ahatch in its top through which access may be had tothe turret from thedeck of the boat. In practice the center of volume of the conning-towerwill be arrangedin substantially vertical alinement with the cen- Y tersof gravity and buoyancy of the boat.

two openings 16 controlled by valves 17 having their stems extendedupwardly into a control' compartment 18, hereinafter described, andprovided with hand wheels.

The compartment 13 communicates with `the middle main ballast-tank 9through an opening 19 controlled by a valve 20 having its stem alsoextended upwardly into the control compartment 18 and provided withsuitable operating devices. The manifold and valves, as well as themanifold and valves (presently described), controlling the admission ofwater to the forward and after middle main ballast-tanks 10 and 11,v

form the subject matter of an application Serial No. 877,409 led by meonf even date hereof and as I herein make no claim to the specificconstruction of the valves and manifolds, I do not deem it necessary todescribe or illustrate them in detail as it -will be .evi-` dent thatvarious v constructions of valves may be employed for controlling thead- Theinner ends of the said ballast-tanks 10 agi 11are provided withducts 21 and 21 resp tively, which are extended into the middle -linainballast-tank and terminate below the'l central control compartment 18 asindicated most clearly in dotted lines in F ig. 2. The ducts 21 and 21communicate with compartments 22 -Fig. 4, formed in manifolds 23,1igs. 2and 4 arrangedjin the middle main ballast-tanks, and like the manifold12, are'formed with compartments 24 which open tothe water of flotationand whlch communicate .with the compartment through openings 24', saidopenings being controlled by valves 25 having their stems extendedupwardly into the control compartment 18 and provided with handoperating wheels 26. The communications in the manifolds between thecompartments 22 and the ducts 21 and 21', respectively, are controlledby valves 27 also having their stems extended into the controlcompartment and provided with operating hand wheels 28. Built within themiddle main ballast-tank at the sides of the Aboat are auxiliaryballasttanks 30, the -c'enters of volume of contents' of which arearranged in transverse alinement with the centers of gravity andbuoyancy of the boat. AThe said tanks 30 are constructed with bottomplates 31 Fig. 3, which are connected airand water-tight to the platingof the'inner and outer hulls, and with sides 31 Fig. 2, which areconnected airand water-tight to the bottom plates 31; to the plates ofthe inner and outer hulls, and to the plates 8, respective1y. l/Vater isadmitted to the auxiliary tanks through openings formed in the outerhull, controlled by valves 33, the stems of which are extended into thecontrol compartment 18 and provided with hand wheels' 34 by which thevalves are opened and closed. It may be` stated here, that as in allsubmarine or submersible boats, the auxiliary tanks are designed forholding sufficient quantities of water to compensate for the differencesin the specific gravity of fresh and salt Water, it beingunderstood,that when the boat is operating in fresh water, thedifference in specific gravity of fresh Water as compared with saltwater7 requires the Withdrawal of water from the auxiliarytanksxii/i'der to put the boat into submerging condition.

Built within the upper end s of the auxiliary tanks are finaladjusting'tanks 35 of smaller capacity that the auxiliary tanksv anddesigned to 4receive water ballast Afor finally adjusting the boat forsubmergence. The tanks 35 are constructed withl bottom plates 36 whichare` connectedjairand water-tight to the inner and outer hull sections,and .with end plates 37 also connected airand water-tightvto the platingof the inner and' outer hull sections,.to the bottomz plates 36, and tothe plates 8 respectively, Water ballast is admitted to the finaladjusting tanks 35 through a common :pipe 38 ing vented through va'pipe4Q connected to 'Y the tops of the :tanks and extendedacross the top ofthe inner hull section withinthe superstructure,fand having a branchwhich is extended into the said inner hull and provided'with a`ventvalve 41 o perable from within the, control compartment.
